WIRE on' non ROLLING MACHINE Application kled July 13, 1922. Serial No. 574,640.

To all whom t may concern.'

Be it known that I, JOHN W. LAUREN, a

citizen of the Republic of Finland, and a resident of the city of Sterling, in the county of Whiteside and State of Illinois, have invented. certain new and useful Improvements in a Wire or Rod Rolling -Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a pai*J of this specification.

It is an object of this invention to provide a machine having a rotor carrying a plurality of rotatable co-operating elements so arranged Aas to define a tapering way therebetween through which the wire is adaptedto travel, be reduced in size and rolled into form.

It is a further object of this invention to provide for the adjustment of the machine for rollingwire or rods of varylng dlameters. i

With these and other objects in view,

which will become more apparent in the following description and disclosures, this invention comprises the novel mechanlsm and combinations hereinafter descri ed and more particularly pointed out and elined in the appended claims.

In the-accompanying drawings, which illustrate a preferred embodiment of this Ainvention, and in which similar reference numerals refer to similar features in the dierent views:

Figure 1 is a central section through the machine with the operating motor in elevation.

Figure 2 is alfront elevational/view of the' a pair of sections 1 and 2. The section l'iis` provided with an extended journal bearing 1* in which an axial and conical opening'or aperture 3 extends which merges into a cylindrical bore 4 opening interiorly of the spider, and a radially extending flange l", having a plurality, four in the present instance, of equally spaced and longitudinally extending abutments l, reversed, curved or 4beveled upon their lower surfaces. The portions ld of the flange intermediate the abutments 1 are provlded with bearing apertures concentrlcally arranged with respect to the axis of the cylindrical bore 4, the axis of said apertures converging rearwardly.l

The spider section 2 is provided with a journal bearing 2a having an axial cylindrical aperture 5 extending therethrough, and a radial flange 2b having a'plurality, four in the present instance, of equally spaced and longitudinally extending abutments 2' reversely curved or beveled upon their lower surfaces. The portions 2d intermediate the abutments 2c are extended inwardly of the section and provided with bearing apertures concentrically arranged with respect to the axis of the cylindrical bore 5.' The axis of the bearing apertures-in the portions 2d likewise converge rearwardly upon the same slope as the bearing aperturesin the portions 1d.

. The spider sections 1 and 2 are adapted to be assembled by means of screw `bolts 6 extending through the longitudinal abutments 15 and 2.A When so assembled, the axis of the bearing apertures in opposite intermediate portions 11 and 2d of the radial flanges are in axial alinement for rotatablyI supporting roller shafts 7, each of which has rigidly mounted thereon a plurality of circular disks lor rolls 8. The rolls 8 n one a1r of diametrically opposite shafts 7 are directly opposite or opposed to each other; the rolls 8 on the other pair of diametricallyl opposite shafts are likewise directly opposite or opposed to'. .each other, but they are staggered in relation to the rolls of the flrstmentioned pair of shafts, as shown in l igs. 1

- and 4. As the axes of the bearing apertures for the shafts 7 converge, the shafts 7 will necessarily converge, and the diameters of the rolls are all equal, a tapering way will be defined between the peripheries of the rolls in alinement with'the boresl 3 and 5 in the spider. The shafts 7 are freely slidable in these bearings and are designed so as to extend only partially in the rear bearings 2d to allow for longitudinal adjustment for increasing or decreasing the tapering way between the rolls for rolling wire or rods of different diameters.A

rEhe spider with the four sets of rollers mounted therein constitutes a rotor which is rotatabl mounted in a housing 9 by means of .the journals 1a and 2a. sleeve 10 having an inner tapering or converging surface corresponding to the convergence of the shafts 7 is mounted for free rotation within the housing 9.

The housing 9 is provided with a lubri cant chamber 12 in lthe lower portion thereof which extends below the radius of the sleeve 10, and suitable grooves are formed in the sleeve 10 in order to admit lubricant within the interior of the sleevev for lubricating the rolls.

The front ends of the shafts 7 abut a ing for the journal 1a of the rotor. The

outer end of the sleeye 14 ,is provided with a groove 'formed by an annular shoulder 16 and a threaded collar 17 for receiving a ring 18 provided with a pair of diametri- 1 callyopposite studs 19 upon which a yoke lever 20 is swiveled, the llower end of said yoke lever bein pivoted upon a lug 21 and the upper end having a screw 22 rotatably anchored therein, which screw engages a threaded opening in a lug 23 projecting from the front of the housing. By rotating the screw 22, the sleeve 14 may -be adjusted longitudinally on the journal 1a carry-` ing the end thrust ybearing with it. By

adjustably sliding the sleeve 14 inwardly,v

the shafts 7 will be shifted rearwardly thereby decreasing the size ,of the tapering way. A reverse adjustment will increase the tapering way, as is .-obvious.

The rotor is adapted to be rotated at a high rate of speed by means of a motor 24 mounted upon the housing and having `a sprocket wheel on its shaft over whichv a sprocket chain 25 which drives a sprocket wheel 26 secured upon the end of the journal 2'of the rotor which extends beyond the bearing bossof the cover plate 27 that closes the rear end of the housing 9, being` secured thereto by boltsl 11.

Inthe operation of this machine, the motor is started to` rotate the rotor. `When A bushing or therethrough. The rod is gradually reduced by the action of the rolls to the proper size desired according to the adjustment of the rolls. rlhe tendency of the bar 28 to become locked between the rolls is overcome by the relative rotation of the rolls and rotor.

At the present time, it is contemplated that the machine to be used for rolling cold steel rods or the\ like which are usually pickled before rolling, but it is apparent that the machine is susceptible of rolling hot steel rods just as well.

. lt is characteristic of this invention that no dies are'needed and that the wire or rods are not injured or distorted by the severe tensile pull unnecessary when the rods are drawn through dies. The machine may be readily designed to accomplish a reduction in one operation that takes several dies to accomplish; thus a great saving of labor andtime is effected by this machine., and a better grade of article is produced.

,I am aware that numerous details of construction may be varied through awide range without departing from the principles of this invention, and 'l therefore vdo not purpose limiting the patent granted otherwise thanv necessitated by the prior art.
